NuSOAP - allowing arrays as inputs

Hi,

Trying to finalise our API and using NuSOAP to generate the WSDL.
I'm having some issues with allowing users to enter arrays as inputs.
This doesn't seem to be a problem using PHP's SoapClient, but when using other languages the WSDL doesn't work.

I've tried the following approaches:

$server->register(
'functionName',
array('parameters' => 'xsd:string',
array('return' => 'xsd:string')),
'namespace'
false,
'rpc',
'encoded'
);

PHP:

$server->register(
'functionName',
array('parameters' => 'xsd:string[]',
array('return' => 'xsd:string')),
'namespace'
false,
'rpc',
'encoded'
);

PHP:

$server->register(
'functionName',
array('parameters' => 'xsd:array',
array('return' => 'xsd:string')),
'namespace'
false,
'rpc',
'encoded'
);

PHP:

$server->wsdl->addComplexType(
'parameter',
'complexType',
'struct',
'sequence',
'',
array(),
array(
'key' => array('name' => 'key', 'type' => 'xsd:string'),
'value' => array('name' => 'value', 'type' => 'xsd:string')
)
);

$server->register(
'functionName',
array('parameters' => 'tns:parameter[]',
array('return' => 'xsd:string')),
'namespace'
false,
'rpc',
'encoded'
);

PHP:

$server->wsdl->addComplexType(
'parameter',
'complexType',
'struct',
'sequence',
'',
array(),
array(
'key' => array('name' => 'key', 'type' => 'xsd:string'),
'value' => array('name' => 'value', 'type' => 'xsd:string')
)
);

$server->wsdl->addComplexType(
'parameters',
'complexType',
'array',
'',
'SOAP-ENC:Array',
array(),
array('ref' => 'SOAP-ENC:arrayType', 'wsdl:arrayType' => 'tns:parameter[]'),
'tns:parameters'
);

$server->register(
'functionName',
array('parameters' => 'tns:parameters',
array('return' => 'xsd:string')),
'namespace'
false,
'rpc',
'encoded'
);

PHP:

Any one got any ideas on how to get this to work?

Sorry, to clarify... what I want to do is be able to input an unbounded array into a soap call.
I've have also tried putting minOccurs and maxOccurs into those examples above.

I'm sure it must be possible.
